FLOOR-SCRUBBING MACHINE.

Application led September 10, 1921. Seria] No. 499,732.

To all 'whom t may concern:

Be it known that I, SILVIO MAGATON, a subject of the King of Italy, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Floor- Scrubbing Machines, of-which the following is a specification. f

This' invention has relation to floor scrubbing machines andhas for an object to provide an implement by which water may be distributed over the floor and the dirt particles dislodged, with means -to absorb the soiled or waste water from the floor and for temporarily storing the waste water in a receptacle forming part of the implement.

i Another object of the invention is to provvide a floor scrubbing implement of the character set forth and embodying a rotatable absorbent scrubbing element, means to hold' the element against rotation so that sufficient friction may be engendered with the ioor to remove the dirt particles therefrom, said element being rotatable to subsequently absorb the soiled or waste water, a means to squeeze said element to expel the waste water therefrom, and a receptacle to temporarily receive the soiled water.

In addition to the foregoing this invention comprehends improvements in the details of construction and arrangement parts to be hereinafter described and particularly v set .forth inthe appended claims.

In the accompanying drawings in whichv l'similar and corresponding parts are designated by the sameV characters of referencev throughout the several views in which they 'formed in the periphery of the disc for a appear Figure 11s a view in longitudinal section of a floor scrubbing implement constructed.

of the sleeves.

With reference to the drawings, 10 indicates the` handle of the implement, and 1'1 a rotatable scrubbing element mounted thereon. In detail, the'scrubbing element consists of a shaft 12, square incross section. A pair of-spaced collars 13are mounted on one end, and the-other endis formed with a reducedv and threaded extension 14C upon which apair of spaced collarsl are placed,

Ythe latter being held on by means of a thumb nut 16. LA sleeve 17 is mountedon each end of the shaft, said sleeves hav-ing square `openings to receive the shaft. y Each sleeve carries a/ehol'low-disc 18, the lattervhaving central openings-to receive the sleeves, and the discs are held in place by means of nuts 19 which are applied to the inner rthreaded ends A ysegment is cut away from each disc leaving a straightdedge 2O along `the chord of the disc, and `mounted inleach disc is a segmental member 21, pivoted at 22, the outer edge ofthe member projecting from Within the disc and forming a complete circle with the balance of theA periphery of the disc. A leaf spring 23 fixed to the member 21 at its pivotal point and bearing against the inner surface o-f the disc acts to urge said member outward.

, The handle construction comprises a rod section 211 cast with anextension 25, the latter being formed with an annular portion 26 in Vwhich a relatively thick disc 27, is held for rotation. Said discis formed with, a square central opening through which the shaft 12 extends, and a plurality of radial-openings or recesses 28 are formed vin the disc to receive one end of a rod 29. VA groove 30 is Vopposite or outer end of which is reduced,

and said reduced portion passed through a tubular member, aknob 33 being subsequently secured on-theouter end of said reduced portion. A spring 34 is embraced about said reduced portion and bears at one end against the shoulder which is located at the juncture,

i ofthe rod 29 with its reduced-portion, and

. p'ortionof the rod 29 normally-rests in a rel material.

cess in the plug 32, and when in this position the rod 29 will be seated in one of the recesses 28. if the rod is slightly withdrawn by grasping the knob 33 and then rotated the inner end of the rod will leave the recess and will enter the groove of the disc, said rod being held in this position by engagement of the pin 35 with the plug 32. rlhis, with the rod 29 in an inward position the disc 27 and consequently the shaft 12 is held against rotation, and by withdrawing the rod the shaft may rotate that Athe seating of the rod intheg'roove30 of the disc will prevent the latter from leaving the annular portion 26 by lateral movement. i The rod section 24 enters a; tube section 36 forming part of the handle.- A block 37 slides within said section 36 and pivoted. tov said block is a pair of arms 38 which arerin diverg'ing relation and pass through the bifurcated ends 39 of across bar 4() which is fixed to/said section 36. A roller 41` journalled within eachbifurcated portion serves to provide an auto-friction means against which the arms 38 may ride and to hold the latter in place. The outer ends of the arms 38 are bent so Aas to extend around the discs 18, and are formed with enlargements 42 which are apertured to receive the ends of the above mentioned sleeves 17, one of which is provided at each end of the square shaft 12. A

finger 43 is formed on each arm 38 beyond the enlargements, and each finger isY slotted to receive a pin 44 extending eccentrically from each disc 18. yA reciprocable member Y45 operates in the outer end of the handle,

and a rod 46 connects said member with the block 37. The scrubbing element consists of a number of units, one unit being shown in Figure 7 and consisting of a disc 47 having a square central opening to receive the shaft 12, and a number of radial fingers 48 secured to the inner edge of an annular member 49 composed of sponge, felt, or other absorbent A number of these units are mounted on the squared shafts between the discs. Formed with the casting 25 is a pairof supports 50, parallel to each other and to the shaft 12. Each support is formed with a pair of apertured lugs 51. A tank 52, semicircular in cross section is provided. A lug 53 is formed at each side of the tank to enter the space between the lugs 51, so that a rod 54 maybe passed through said lugs 51 and 53 to hold the tank in place. A recess 55 is formed in the concave side of the tank and said recess is formed with an aperture 56 against which a ball valve 57 is held by gravity when the implement is held in an operative position, a cage 58 being provided to retain the valve in place. A brush 59 is held within a guide 60 mounted on the convex side of the tank. A cap 61 covers an opening in the end of the tank through whichits contents may be discharged, A slotted finger 62 is mouned at each end of the tank, said fingers receiving the ends of the shaft 12 between the collars 13 Vand 15, thus affording a steadying means for the tank.

In operation, the shaft 12 is locked against rotation and the floor is moistened and the moisture spread by means of the scrubbing element 11. The implement is supported with the handle at an angle and the tank 52 on the upper side. it will be noted that the segments 21 will slide into the discs. when contacting with the' floor., thus permitting the scrubbing element to engage the floor. After' the dirtl particles have been dislodged the shaft 12 is unlocked. The scrubbing element may now rotate and by moving the implement over the floortthe soiled water is absorbed by the units of the scrubbing element. `When said element is saturated. the implementis turned over to bring the tank on the under side. The member 45 is now pulledout and the arms 38 intriding against the rollers 41 will force the discs 13 toward each other, thus squeezing the units ofv the scrubbing elements between them and eX- pelling the waste water which will iiow into the tank through' the opening 56, the valve 57 being unseated in this position of the tank.

Having thus described my invention, which l claim as new and desire to secure by United States Letters Patent is:

l. A scrubbing .implement including a support, an absorbent scrubbing element carried thereby for rotation, means to lock the element to the support against rotation, a handle, a pair of members mounted thereon to engage said element between them to expel the water from the element by compressing the same when the members are moved together.

2. A scrubbing implement including a support, a shaft, a plurality of absorbent elements mounted on the shaft, means to lock the shaft against rotation, and means to compress said elements and to move them toward each other along the shaft to expel the moisturejtherefrom.

3.
